vim - 为什么我可以通过使用井号 (#) 来破坏 vim 用户函数命名规则

Question

vimscript 帮助文件声明在定义用户函数时:

The function name must start with an uppercase letter, to avoid confusion with builtin functions.

这是强制执行的，除了我通过查看其他人的代码发现的以下情况。

"This should not work.
"But it does as long as the function is in a file called 'overrides.vim'.
function! overrides#name() abort
  echo 'Test overrides\name'
endfunction

"This should not work either.
"But it does as long as the file above is in a folder called 'plugin'.
function! plugin#overrides#name() abort 
  echo 'Test plugin\overrides\name'
endfunction

let stupid = {}
"This should not work.
"But it does aslong as the stupid Dictionary is defined.
function! stupid.name() abort
  echo 'Test stupidname'
endfunction


call overrides#name()
call plugin#overrides#name()
call stupid.name()

我到处寻找可以解释这种语法的任何东西。我知道这现在有效。我很好奇的是，对于你们中使用过这种语法的人，你们是从哪里了解到的？

帮助文件中是否还有其他未提及的 vimscript 功能？

此命名语法适用于 autoload功能。类型 :help autoload-functions求助。

AUTOMATICALLY LOADING FUNCTIONS ~
                                                          *autoload-functions*
When using many or large functions, it's possible to automatically define them
only when they are used.  There are two methods: with an autocommand and with
the "autoload" directory in 'runtimepath'.
